Double death of the sharks are

at the hospital entrance, often see some people giving out the kind of shark cartilage powder Small ads often see patients believe these ads cost a lot to buy the eat.Shark Cartilage, sounds like a very expensive drug it, so effective in the end do?

us look at the evaluation of American Cancer Society: Most shark cartilage products in the form of tablets or powder as a dietary supplement (Writer's note: In China called health products) sales.Most of which did not effect the safety inspection, nor verified the purity of ingredients.The current scientific evidence does not support the sale of shark cartilage as a food supplement products can be effective in treating cancer, osteoporosis or any other disease.

If so, that is how people believe that shark cartilage products that they can treat tumors that?

there is a wider spread of tumor argument is not a shark, so eating shark cartilage to treat cancer.This argument is based on a long eat what you eat anything or eat anything change what absurd theory; According to this logic, we humans eat so many plant foods, should have to grow themselves photosynthetic chlorophyll role.Gengrang supporters feel then this argument is, in fact, the shark will of tumor.

Kaopu there is a point to say that shark cartilage contains substances inhibiting angiogenesis, eat after the abnormal blood vessels around the tumor can inhibit the formation of tumor blood vessels lack of nutrition, will be hungry dead.This refers to the principle of medicine is somewhat similar to some drugs, so even many medical professionals have also high hopes for shark cartilage.In the laboratory, concentrated extract of shark cartilage can indeed inhibit tumor angiogenesis; but unfortunately, the real treatment out of the lab onto the battlefield, shark cartilage really soft, and can not be displayed on the human anti-tumor effect.

practice in drug research and development this is very common, the laboratory performing well, applied to humans have shown no effect, because, after all, and the medium is different from a simple tube, but also Unlike mice, dogs of these experimental animals.Therefore, the completion of many drugs in vitro studies, in animal experiments has not been proven effective and to be eliminated; or after completion of animal experiments, conducted in humans have not been proven in clinical trials, efficacy has been eliminated.Finally, the drugs enter the market really is far less than the effect found in the laboratory.

saw shark cartilage are also facing the fate of being eliminated, then there was the emergence of cattle to save it.The cattle were named William? Ryan, who he co-wrote a book, not a shark of tumor (now we know that the sentence is wrong), but also by the United States the greatest impact on the CBS TV, fire a handful of (writing a book, on TV, this combination of boxing, we'd like the way the country is somewhat similar to many masters.) Then Ryan and his son started a company, the production of shark cartilage products.

Rennes down the road to make a fortune and his son also is not smooth, because the United States have a strong FDA (Food and Drug Administration).Reasonable to say that drugs proven effective in clinical trials before the drug can no one on sale.But the company side of Rennes use books, newspapers and websites hype shark cartilage products can treat cancer and other diseases, side of the original can only be used to sell this drug in patients.FDA and the U.S.Federal Trade Commission has issued a warning to the company, prosecution and ordered them to stop the false propaganda and its fine, but the company did not stop these illegal activities.In 2004, the court Rennes company to stop selling shark cartilage products and their other similar products, except the destruction of all stocks other than research purposes, and issued a ban on the products that they will be false propaganda, or may face imprisonment punishment.

some pharmaceutical companies see the road that leads to nowhere, health care products began to hit the edge ball (the United States called dietary supplements), because dietary supplements do not need FDA approval to market.For health care products can not claim to have a therapeutic effect even more, but these businesses do not want to give up for promotional and publicity, leading many patients believe that this product is a panacea that would cure cancer, rather than optional health care products.On the Internet now can see many of these promotional and sales information, it seems FDA and the Federal Trade Commission and merchants Catch will continue.

on earth there are many different plants and animals like sharks because of unwarranted, or exaggerated the effect of the siege tragically human.They did not give the sacrifice of mankind to imagine the benefits, it may be wasted step.Besides, they probably would not be willing to be sacrificed.Meanwhile, the superstition of shark cartilage in cancer patients may miss the chance of receiving proper treatment, some patients have been shown to give an effective radiotherapy and chemotherapy, and prefer the shark cartilage product, the end result of course, tragic.Both humans and sharks become the losers in this game.
